The ADE-OS and ACS 5.2 software run either on a dedicated Cisco 1121 Secure Access Control System (CSACS-1121) Series appliance or on a VMware server. However, ACS 5.2 continues to support CSACS-1120 appliances that you have used for ACS 5.1 and that you would like to upgrade to ACS 5.2.

For VM-based installations, you need to configure the VM environment to meet minimal system requirements as well as install the ACS 5.2 software. The supported VMware versions are ESX 3.5 and 4.0.

ACS 5.2 is compatible with ADE-OS 1.2. If you are using ACS 5.0, you must upgrade to this ADE-OS version as part of the ACS 5.2 upgrade.

Warranty, service, and support information is located in the Cisco Information Packet that shipped with your appliance.
